Possible Cause Solution
Fault Type
Motor auto-tuning
fault
E19.02
E19.04
Auto-tuning on the
synchronous motor magnetic
pole position angle fails.
Check whether the motor is disconnected or output
phase loss occurs.
Axis fault
E19.05
Auto-tuning on the
synchronous motor magnetic
pole initial position angle
fails.
Increase the synchronous motor initial position angle
detection current (F2-29).
Axis fault
E19.06
E19.07
E19.08
Auto-tuning on the stator
resistance fails.
Ensure that the motor is connected properly.
Ensure that the rated motor current (F1-03) is set
according to the motor nameplate.
Axis fault
E19.09
E19.10
Auto-tuning on the
asynchronous motor
transient leakage inductance
fails.
The motor is not connected or output phase loss
occurs. Ensure that the motor is connected properly
or the motor is disconnected from the load.
Axis fault
E19.12
The auto-tuning times out.
The motor is not connected or output phase loss
occurs. Ensure that the motor is connected properly
or the motor is disconnected from the load.

Axis fault
E19.15
Axis fault
E19.16
Axis fault
E19.17
Axis fault
E19.19
Axis fault
E19.20 Auto-tuning on the zero
position angle of the no-load
synchronous motor times
out.
Check the Z feedback signal.
Axis fault
E19.22
Axis fault
E19.23
Auto-tuning on the
synchronous motor pole
position fails.
Ensure that the rated motor current (F1-03) is set
according to the motor nameplate.
Decrease the synchronous motor initial position
angle detection current (F2-29).
Axis fault
E19.24
Auto-tuning on the
asynchronous motor
transient leakage inductance
fails.
The AC drive power rating is too low.
Select an AC drive of proper power rating according
to the motor power.
Axis fault
EEPROM read-write
fault
E21.01
EEPROM read-write is
abnormal.
For parameters written to EEPROM through
communication, check the RAM addresses of the
parameters. For the RAM address mapping of
parameters, see "Parameter Address Rules".
If the EEPROM chip is damaged, contact the
manufacturer to replace the main control board.
